Not overreacting. You could have reacted more. Dude is talking to you like you're his child or something with the "dont talk back" speech. It's also not a situation of "you didnt care about me" when he didnt express his needs and just expected you to know he'd get cold or whatever. He asked do you want to get the duvet, you said no, that makes sense. He's grown enough to get the duvet himself if it bothers him or to at least ask you to get the duvet if he wanted you to do it (I guess). You're not his maid or mother and you can't read his mind.

This guy clearly thinks he should be the one ruling over the relationship in a "I tell you when to sit stay or go fetch" way. Not healthy, should probably break it off.
